Exchange / Outlook 2007 Upgrade from 2003 - Assigned Tasks updates lose Color Category Information
I am upgrading our Exchange 2003 environment to 2007. All clients are running Outlook 2007, regardless of which Exchange Server their Mailbox resides on.
After moving a user from Exchange 2003 to Exchange 2007, any assigned Tasks that they flag with the new "color categories" have a problem.
Let's say I create a Task Request, and send the request to User B. Whenever User B sends any update to the task, including simply accepting the Task Request, the item becomes uncategorized in my Task List. So basically I have to re-categorize any assigned tasks whever anybody sends an update for that task.
Apparently this behavior is only occurring with users who have been transitioned to Exchange 2007, so it isn't an Outlook 2007 thing...the clients have been doing this with Outlook 2007 and Exchange 2003 for months with no problems.
